asp.net和VB.net中的图表 [英] Charts in asp.net and VB.net

问题描述

我想创建一个带有updatepanels的网页，每页显示12个图表.
数据从链接到excel命名范围的访问数据库中拉出.
这是正确的方法吗?是否可以显示这么多带有计时器的图表，以将更新面板更改为下一张工作表?
希望有人可以给我更好的解决方法.

谢谢
Joe

Hi,

I would want to create a webpage with updatepanels showing 12 charts in each page.
The data is pulled out from an access database which is linked to excel named ranges.
Is this the right method and is it fine to show so many charts with a timer to change the update panels to the next sheet?
Hope that someone could give me a better approach to this.

Thanks
Joe

推荐答案

是否太多取决于运行站点的硬件.可以考虑让用户单击启动刷新过程的按钮，而不是使用计时器自动刷新.此外，没有理由您不应该将每个图表的计算/渲染过程都局限于它自己的线程，而将图表本身放入ajax更新面板中.如果您不关心非Windows框，则应真正考虑使用Silverlight.这是一个更加丰富的平台.

Whether or not its too many depends on the hardware you''re running the site on. Instead of using a timer to auto-refresh, consider letting the user click a button that starts the refresh process. Further, there''s no reason you shouldn''t be able to have each chart calculation/render process confined to it''s own thread, and put the charts themselves into ajax update panels. If you''re not concerned about non-windows boxes, you should really consider using Silverlight instead. It''s a MUCH richer platform.
